In the past few years, we have covered plenty of cool levitating speakers and app connected toys here. The Quantum Solar System is also worth a look. It is a levitating platform with planets that orbit around a tiny sun that doubles as a lamp. What’s neat is the fact you can sync the position of the planets with NASA in real-time.
You can position the planets at any date in the past or future. It is also possible to speed up time to see them orbit the sun faster. This tiny solar system comes with iOS/Android app control. It will have an API for developers. The app lets you customize the position of the planets and change speed.[where to get it]
